Pregnancy Test Sensitivity

[Mammabear31]

I'm feeling a bit confused this morning. I thought the higher the u/ml the more sensitive, have recently been using 25 u/ml. However I have read the below on another website and now I'm confused?

The sensitivity of a pregnancy test is described on the packaging as mIU/ml (milli-International Unit per millilitre). Pregnancy tests range in sensitivity from 10mIU/ml to 40 mlU/ml. The lower the number, the more sensitive the test, and the earlier it can detect pregnancy.

Is that correct?? If so I've been doing this all wrong!!

The lower the number, the more sensitive the test

It refers to the lowest amount of hcg that it will detect in your urine, so as oblivious states - the lower the number, the more sensitive it is.

Okay feeling really, really stupid now. Thank you all!!
